    You can run either the black or green top but the Black Top is the best one in regards to no issues. I'm currently running the black top and my shop skipped the RRE wiring harness (I recommend you get this though) as he simply spliced and wired it to the harness connection himself. I'm currently running a 2g head/6 bolt bottem end combo btw :thumb:

    So black top CAS and the RRE wiring harness. Is there any big problems after that? Do i got to mess with my computer or anything?

    6 Bolt Motor Install Into a 2G Eclipse

    Is this the harness. I have a stock block not 6 bolt. I just want the CAS on the right side on my 95 eclipse.

    "It connects to a 91-94 1G Eclipse CAS on one side and at the other end it plugs into your 2G wire harness where your old 2G cam and crank angle sensors would have in order to give a cam and crank position signal to the ECU."

    That should be all you need.

    yes i just got my harness in and am getting a CAS for my cylinder head. I had some questions. I read after you install the harness and CAS you have to change pins on the ECU? is this true? And if so is there a write up on changing the pins?

    I have the harness and i just bought the black top CAS yesterday.

    I didn't use the harness and didn't need to and neither did my 450475 friends that have done this. I know the how to says something about it but all I did was change my firing order.

    With or without link, none of us had to change any pins.

    If you are picky like me, Just swap the wires at the back of the coils and leave the plugs order as it is.
    I did it this way so I can leave the spark plug wires routed on the spark plug wire clips, so the wires are not all over the place.

    Not to thread jack at all, but say someone isnt running DSM link, and maybe running an H8 flashable ECU. Would they follow the same procedure for firing order as with link? i.e. swap wires.

    Ok so today i got my black top CAS and i got the harness also. So now i was wanting to know on the install of the CAS? i know it can be 180* out and how can i tell if i am installing right? also should i get a new O-ring for the CAS? I have been reading for a couple weeks on these questions so if you can help that would be great. thanks :hellyeah:

    set you motor up on TDC with all your timing marks lined up look at the CAS it has a notch on the cam drive blade it lines up with the mark on the housing that puts it on top dead.
